A critical session management vulnerability in PHPGurukul Doctor Appointment Management System v1 permits unauthorized session hijacking, posing a significant risk to user account integrity.

The application fails to properly invalidate sessions within the /doctor/change-password.php component, which allows an unauthenticated attacker to perform session hijacking.

Successful exploitation of this vulnerability enables an attacker to hijack active sessions, leading to unauthorized access to sensitive administrative or user functions. Given the CVSS score of 7.5, this high-severity flaw threatens the confidentiality and integrity of medical data and administrative workflows, potentially resulting in significant data exposure and reputational harm.

Immediate Action: As no official patch is currently available, administrators should restrict access to the affected management interface via network-level controls or by disabling the vulnerable component.

Proactive Monitoring: Review web access logs for unusual patterns or multiple password change attempts originating from non-standard IP addresses, as these may indicate attempted session manipulation.

Compensating Controls: Deploy a Web Application Firewall (WAF) to filter malicious requests directed at the /doctor/change-password.php endpoint and monitor for suspicious session tokens.

Public Exploit Available: Yes, a published proof-of-concept exists, as documented in the research repository referenced by the CVE record.

Given the availability of a proof-of-concept and the high-severity nature of session hijacking, organizations running PHPGurukul Doctor Appointment Management System v1 must prioritize securing the affected environment. Since a formal patch is not yet confirmed, implement strict access controls immediately to prevent unauthorized access until a vendor-supplied update is verified and applied.
